Preparations

CAUTION: New software can only be ordered after the control module has been installed in the car. VADIS reads off the new control module identity which is required to order the correct software.

Always check that the control module and control module box connectors do not have bent or damaged terminals or socket/sleeves. This may have been the cause of the fault.

Removing the control module







The rear electronic module is a separate unit in the relay box in the cargo compartment.
- Remove the integrated relay/fusebox.







- Unscrew the screw holding the connector so that it is free of its threads. Check that the screw is free using your fingers
- Disconnect the connector. Use an open wrench and a support. See the illustration.

NOTE: Do not damage the terminal pins.







- Remove all relays and shunts bridged to the control module. Note the locations.







- Release the catch on the rear. Use a screwdriver
- Lift and pull out the control module.

Check
Check that the control module connectors are intact.

Installing the control module
- Press the control module into place so that the catch on the rear engages
- Position the connector. Carefully press the connector down.

NOTE: The pins are fragile. Check that the connector goes straight down into the control module.

- Tighten the screw for the connector
- Check that the connector cover is correctly positioned. Remedy if necessary
- Install the relays and shunts.
